While one of this week's main storylines revolved around Penny and Leonard (Lenny? Peonard?), we also got treated to the rare partnerships of Sheldon and Howard, and Raj and Amy. Sadly this meant we only saw little of Bernadette, but that's the problem with having seven main characters.

However, by having three different storylines playing out rather than the usual two, it did mean it felt like they never quite got going or had enough time to play out properly, but they were still largely enjoyable.

It looked as if it was going to be yet another Penny vs Leonard relationship crisis at the beginning of the episode when Leonard worries about Penny turning down a part in Serial Apeist 2, despite having no job and living off savings.

Thankfully, they didn't constantly argue or bicker, and Leonard proves his love for Penny by buying her a car after hers breaks down, so that she can drive to auditions and not go back to being a waitress.

It would have been a bit of a cop-out if Penny ended up as a waitress so soon after getting 'The Fear', so it was great to see Leonard saving her and her taking the gift gracefully.

Meanwhile, Howard realizes that despite knowing Sheldon for 10 years, the pair of them never really hang out or get on. Now that Howard is an astronaut and becoming one of the more mature members of the group, he decides to attempt to salvage their friendship by taking Sheldon to Texas for a NASA trip.

As expected, Sheldon's quirks soon begin to irritate Howard on the plane, especially when he belittles Howard as a fully fledged astronaut. Just as it looks like their friendship is doomed, turbulence on the plane forces the pair to hold hands and share their love and respect for each other.

This pairing was probably the most enjoyable this week, especially when they shared a genuine bromance moment. It would have been cool to see them actually in Texas but sadly we only had 19 minutes to cover.

Finally, Raj is convinced by Amy to give online dating yet another go, and eventually asks her to chat to a girl he likes as he seems useless at chatting online. It turns out that the girl isn't quite right for Raj but shares a lot of interests with Amy.

After Raj bursts into Amy's coffee with the girl, she understandably gets rather freaked out and leaves. Yet another girl runs away as fast as possible from Raj.

Raj's quest and failure at finding a lover is becoming a bit of an old gag now, especially as he can finally talk to women without alcohol. What happened to Yvette the vet? She was genuinely up for him and he had her number! Was this just another example of BBT episodes totally ignoring past moments?

This week's episode didn't have many genuine laugh out loud moments but it was an enjoyable one. We just need Raj to finally find someone that could fit in well with the group, or at the very least bring Stuart in from the cold to even out the numbers.

Sheldon's Bazinga of the Week: [When Howard points out he works at the same university as Sheldon] "Yes but Hawkeye is in The Avengers and no-one says, 'Help Hawkeye'."

Other awesome moments:- Penny: "I don't think Meryl Streep ever said, 'Must keep gorilla hands from killing again!'"- Last week's dinner table didn't last long!- Howard calling Sheldon C3P-Wee Herman- Raj: "Judging from her lack of Adam's apple, she has been a female all her life"- Sheldon to Howard: "If you weren't there there'd be a hole in my life, kind of like when Firefly was canceled, but not as big."
